Lefiq Glass Cleaner SurfPurge14

Lefiq Glass Cleaner SurfPurge14

 Description:

Lefiq SurfPurge 14 is a mixture of different inorganic and organic cleaning solutions with pH higher than 14.

Application:

Majority of SurfPurge 14 applications are related to surface cleaning of wafers as well as cleaning of glass disks in Hard Disk Drives (HDD). Formulation of SurfPurge 14 allows it to clean glass surfaces in an extremely short period of time for any bonded or loose particles. SurfPurge 14 is also formulated such that by forming a partial zeta potential no suspended particle in the solution can subsequently be attracted back to the glass surface during the Di-Water rinsing step.  For more information, please contact us.

Cleaning process:

  • Process temperature is about 20 to 25 degrees C.
  • Mechanically agitating the cleaning solution or performing the cleaning process within a Sonication, or use of spray system is highly recommended.
  • Initially, soak wafers or disks in a 1:80 dilution of this solution (SurfPurge14: Di-water) for 30 seconds in order to get rid of all loose particles and to increase the lifetime of the actual concentration of your cleaning solution in your cleaning process.
  • After the initial step above, expose wafers or disks to SurfPurge 12 cleaning solution in a 1:10 dilution (SurfPurge14: Di-water) for 40 to 60 seconds.
  • Rinse your wafers or disks several times with warm Di-Water to get rid of cleaning solution residue.
  • Dry your wafers or disk immediately to eliminate airborne contamination.
